BIG FUN
To all of you trying to squeeze that extra little something out of the Crumble, boy do we have something for you!
Allow me to introduce the Big Fun, our aggressive trail, or maybe just “enduro” hardtail. This is our take on the trifecta known simply as “LLS”. Long. Low. Slack. We built this model around a proven geometry that’s ready to take on any trail you can throw at it, and then some. Build your bike with a 140mm fork for a solid trail rig, or mount a 160mm fork and push yourself to the limit. Enduro hardtails are so much fun, seriously.
The Big Fun borrows a ton of tech from our still-top-secret full suspension trail-duro bike, like a huge ZS44/ZS56 headtube, and custom drawn tubing for all the durability with none of the trail chatter.
All of this, handmade!
Please note:
- All frames are made in Germany in our workshop now.
- Production will happen on a quarterly basis with delivery times being between 8 and 12 weeks.
